Senegal, Sorghum, 2018

Senegal's estimated postharvest losses for sorghum in 2018 was 26,186 tonnes or 11.6% which had an estimated value of more than 12 million US dollar, which corresponds to 0.4% of national agricultural GDP.

As for nutrition 90 billion kcal were lost, which is the equivalent of more than 108 thousand people, in terms of annual nutritional dietary energy requirements. In the value chain, the majority of the loss is estimated to be happening at Harvesting/field drying, Threshing and Shelling, and then Market storage. Highest estimated postharvest maize losses in tonnes were estimated to occur in Kaffrine.

Value chain

Production quantity and estimated postharvest losses in % per value chain step. Please note that once loss has occurred at harvesting, the percentage loss in the next stage is a percentage of what remained, not of the original amount.
